Machine head for guitar

Abstract

Disclosed is a machine head for a guitar. The machine head comprises a clamping section which has a tuning peg and a clamping cap. The tuning peg is defined with a first insertion hole, which extends in a transverse direction and through which a guitar string is inserted, and a second insertion hole, which extends in a longitudinal direction and is communicated with the first insertion hole. The tuning peg is formed on a circumferential outer surface thereof with an externally threaded portion. The clamping cap is formed on a circumferential inner surface thereof with an internally threaded portion and has integrated therewith a clamping member. The clamping member is inserted through the second insertion hole and has a lower end of a semi-spherical configuration.

What is claimed is:  
     
       1. A machine head for a guitar, comprising: 
       a clamping section having a tuning peg and a clamping cap;  
       the tuning peg being defined with a first insertion hole, which extends in a transverse direction and through which a guitar string is inserted, and a second insertion hole, which extends in a longitudinal direction and is communicated with the first insertion hole, and being formed on a circumferential outer surface thereof with an externally threaded portion;  
       the clamping cap being formed on a circumferential inner surface thereof with an internally threaded portion and having integrated therewith a clamping member which is inserted through the second insertion hole and has a lower end of a semi-spherical configuration; and  
       a release preventing section which includes an extended portion, a release preventing ring and a receiving groove, the extended portion being formed on an upper end of the tuning peg, the release preventing ring being fitted around the extended portion and the receiving groove in which the release preventing ring is received being defined on the circumferential inner surface of the clamping cap at an upper end of the internally threaded portion.  
     
     
       2. The machine head as claimed in  claim 1 , wherein the second insertion hole extends through the first insertion hole in a manner such that a lower end of the second insertion hole has a level which is lower than that of the first insertion hole. 
     
     
       3. The machine head as claimed in  claim 1 , wherein a diameter of the clamping cap is no greater than that of the tuning peg. 
     
     
       4. A machine head for a guitar, comprising: 
       a clamping section having a tuning peg and a clamping cap;  
       the tuning peg being defined with a first insertion hole, which extends in a transverse direction and through which a guitar string is inserted, and a second insertion hole, which extends in a longitudinal direction and is communicated with the first insertion hole, and being formed on a circumferential outer surface thereof with an externally threaded portion;  
       the clamping cap being formed on a circumferential inner surface thereof with an internally threaded portion and having integrated therewith a clamping member which is inserted through the second insertion hole and has a lower end of a semi-spherical configuration; and  
       a coupling section which includes a circumferential groove, a fastening ring and a coupling groove, the circumferential groove being defined adjacent to an upper end of the clamping member, the fastening ring being fitted into the circumferential groove and the coupling groove in which the fastening ring is engaged being defined on the circumferential inner surface and adjacent to an upper end of the clamping cap.  
     
     
       5. The machine head as claimed in  claim 4 , wherein the second insertion hole extends through the first insertion hole in a manner such that a lower end of the second insertion hole has a level which is lower than that of the first insertion hole. 
     
     
       6. The machine head as claimed in  claim 4 , wherein a diameter of the clamping cap is no greater than that of the tuning peg.
